Proprioceptive inaccuracies in healthy controls, never treated PD patients, and both groups of PD patients in the “off” state
| Controls (n=6) | Untreated (n=5) | Dyskinetic (n=11) | Non-dyskinetic (n=6) | |
| Side to side elbow comparison: incorrect trials | 4.6 (3) | 6.3 (2.5) | 5.3 (3) | 6.3 (1.7) |
| Matching contralateral elbow: angular error | 3 (0.8) | 3.9 (2.7) | 3.3 (1.2) | 3.7 (1.8) |
| Proprioceptive recall: | ||||
| Spatial error (cm) | 7.1 (2.2) | 6.5 (1.6) | 6.7 (1.7) | 8.1 (3.2) |
| Distance error (cm) | 0.7 (0.9) | 1.1 (1.3) | 0.7 (1.3) | 0.7 (1.5) |
